The A718 is a monolithic switching regulator designed to drive high power LEDs with constant current and is suitable for automotive, industrial, and general lighting applications. The step-down (Buck) regulator contains a high-side N-channel MOSFET switch with a current limit of 1.5A in typical. Hysteretic controlled on-time and an external resistor allow the
converter output voltage to adjust as needed to deliver a constant current to series and series-parallel connected LED arrays of varying number and type.
